Dear Friends,
Can you help me? I am working with RF Rx & Tx module, connected Rx Data pin with RxD of 8052 and Connected Tx Data pin with TxD of another 8052.
I am unable to interface it means not getting data on receiver side?
Is there any need of Antenna? Is yes then can i make that antenna?
Please help me.
RF 434MHz of both Rx & Tx from HIMARK Company.
Thanks & Regards Ramesh Khokhani.
Easy to check if the circuit should have RX to RX and TX to TX or if it should be RX to TX and reverse.
If the transmit pin of the processor can't change between good low and high signals, then two outputs are connected together and are fighting.
agreed, but I'd not recommend the method. If "the fight" goes on long enough (which sometimes is not very long) it will weaken or pop one or both the outputs.
There is no excuse for not reading the datasheet(s) before starting.
